T 0 all whom it-may concern:

Be it known that I, SvEN GUsTAr WING- UIs'r a subject of the King of Sweden, residing at Grottenborg, in the Kingdom of Sweden, have invented certain new and useful Improvements in BallBearings,of which the following is a specification. This invention relates to a ball hearing so arranged that its inner parts, consisting of the balls and of rings, around which the balls run, can be mounted into the outer part,'which also is ring shaped and made integral, and removed from the same without screwthreads being first detached. One object of the invention is to provide a self-adjustable .and self-contained ball bearing simple in construction and economical to manufacture and serviceablein use, and which will take-up-both radial and axialthrust,

-'In the drawings accompanying this speci--v fication' the invention is practically illustrated, wherein.

Figure 1 is an axial section of a-bearing constructed according tothe present improvements; Fig. 2 is a similar view of another form of the device; Fig. 3 is a similar view wherein a single set of balls is provided for receiving theaxial thrust, and a single set for sustainingthe. radial load; and Fig. 4 is a detail illustrating the assembling and disassembling of the parts. I I

In bearings which are subjected to great strain,--more than two sets of balls may be used for-sustaining the load, preferably four sets, so arranged that two sets are subjected substantially to tlie radial pressure and the other two' sets .bstantially to the opposite axial pressure. Such a bearing is shown in Fig. 1. Four sets of balls 10, 11, 12, 13 are located one behind the other longitudinally of the shaft or hearing. The main bearing member comprises a ring 3. Two sets of balls are located at each side of the ring 3,

respectively, 'The outer ball sets'lO and 13 whichrings are contained inan outer sleeve 8. The shaft ispassed through the ring 3 and is supported'by the same longitudinally.

The outersurfaces of the rings 6,7,.b'ea1ing.

"against'the inner side of the sleeve 8, form parts of a sphere the center point of which sleeve, thus rendering the bearing self-adusting and permitting the inner parts to be easily mounted into the sleeve and removed from the same without deforming any part of the bearing, the sleeve being shown'provided with recesses for permitting such removal when the rings 6 and 7 are placed at substantially right angles to the sleeve. The

ball setslO and 13 bear the radial load of the shaft. The two inner ball sets 11 and 12 are subjected substantially to the opposite axial pressures. For that purposethe inner ring 3 is provided on its outer side with a flange 3*", in the opposite sidesof which grooves are provided forthe ball sets respectively,

which besides bear against the rings 6 and 7 respectively. In this case the sides of the said'rings, facing each other, form races for the balls. The balls 10 and 13 are, prefer- I four sets of balls 14, 15, 16, 17 'twosets on ably, somewhat greater than the balls 11 and 12. Also the bearingshown in Fig. 2 has I each side of the equatorial center plane of the ring 3. In this case, however, the rings 6 and 7 are so shaped. inside, that the two central ball sets '15, 16 are subjected substantially to the radial pressure, While the outer ball sets 13, 14': are subjected sub-' stantially to the opposite axial, pressures.

The 'inner'side of the rings 6 and 7 respectiVely, viewed in cross section, is curve shaped and incloses both the ballsets, so

that the groove of the ring is "common to both the sets. The said arrangement may be modified in such manner that the two ball sets run in separate grooves provided in'the ring, as is'the case at the ring 3 shown'in g l In thebearing shown in Fig Bjthe inner ring also forms an outer ring, so that there c are only two rings n the bear ng. 'Theinner ring is provided with an outer flange 7", adapted to'serve as one (7 of -theouter.

rings mentioned above. One 18 ofthe ball sets 18 and 19 is subjected to the radial press 3 sure, while theother set 19, located between f :the ring 6 and the flange T, is subjected-to the'axial pressure. In. a bearingvof this I character it is particularly desirablethat the outer rings 6, 7 be properly positioned one in respect of the other and both in respect of the inner bearing member 3. This in the present instance 1s accomplished by the spherical faces upon the outer surfaces of the-rings 6, 7, engaging the inner spherical face upon the containing ring 8. This of course in connection with the proper cage of balls will assure the accurate location of the parts. The outer ring not only serves as a bearing for permitting the self-adjustment of the inner portions of the device, but also as a means forbondin'g the various parts together in their proper positions. The stability of the device is assured by the fact that the-members 6, 7, engage the outer n that there is a set of balls on each of such faces engaging'the/outer member.

This appllcatlon is a division of my co- )ending applicationSerial No. 615,339 filed arch 18, 1 911, for ballbearings.

It will be readily understood that the bearings herein shown and described are illustrative of the invention, and that changes may be made within the scope of the claims without departing from the spirit of the invention.

I claim as my invention 1. In a ball bearing thecombination of four sets of-balls, an inner bearing ring for the ball sets, two of the said sets being located on each side "of the equatorial center plane of the ring, two outer bearing rings formingraces for each pair of ball sets, and an integral outer sleeve, inclosing the said outer bearing rings, there being spherical integral outer sleeve, inclosing the said sleeve and outer bearing rings and the sleeve being so shaped with relation to the outer bearing rings, that-the latter, forming an angle with the sleeve, can be inserted into and withdrawn from the same, substantially as described and shown in the draW-' ings.

2. In a ball bearing the combination of an inner bearing ring, four sets of balls bearing against the said ring, two of the said sets being subjected substantially to a pressure longitudinally of the shaft and bearing against outer rings respectively, and the other two ball sets subjected substantially to a radial pressure and also bearing against the said outer rings respectively, and an outer lntegral sleeve inclosing the said outer bearingrings, there being spherical contact surfaces provided between the outer rings and the sleeve and the latter being so shaped that the outer bearing rings located at an angle to the sleeve canibe inserted into or withdrawn from the same, substantially as described and shown in theldrawings.

3. In a ball bearing the combination of two ball sets, one subjected substantially to the pressure longitudinally of the shaft and the other to the radial pressure, bearing rings for the said ball sets, and an outer, integral sleeve inclosing the said outer hearing rings, there being spherical contact surfaces provided between the sleeve and the bearing rings and the sleeve being so shaped, that the outer bearing rings, located at an angle to the sleeve can be inserted 'onto or withdrawn from the same, substantially as described and shown in the drawings.
